Certain PHP configurations may limit exposure to this issue. This issue may be mitigated by setting 'all_url_fopen' to 'off' when configuring PHP. Currently we are not aware of any vendor-supplied patches for this issue. If you feel we are in error or are aware of more recent information, please mail us at: firstname.lastname@example.org .
W-Agora is prone to an issue which may allow an attacker to include arbitrary files located on a remote server. In particular, the 'inc_dir' variable found in a number of the W-Agora scripts defines the path to the configuration file. It is possible, under some configurations, for an attacker to specify an arbitrary value for the location of the configuration file which points to a file on a remote server.
If the included file is a PHP script, this may allow for execution of arbitrary attacker-supplied code.
w-Agora contains a flaw that may allow a remote attacker to execute arbitrary commands or code. The issue is due to the scripts in the 'include' and 'user' directories not properly sanitizing user input supplied to the 'inc_dir' parameter. This may allow an attacker to include a file from a third-party remote host that contains commands or code that will be executed by the vulnerable script with the same privileges as the web server.
Upgrade to version 4.1.4 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
